Remove the servo arm from
the servo and thread the ball
link onto the pushrod.
Repeat this process for each
of your servos – on each con-
trol surface.
Once you have all the servos mounted, it is a good idea to use a
matchbox or other equalizing device, so that there is no binding in the
servos. If such a device is not used, extreme care must be taken to me-
chanically match and adjust servo and linkage geometry to avoid bind-
ing, or servos fighting each other. If this step is overlooked or not per-
formed with care, loss of control of model is very likely.
This goes for all control surfaces with multiple servos.
